The student can improve the investigation by dropping the balls from the same height. This ensures that the only variable being tested is the mass of the objects, allowing for a clearer understanding of how mass affects the drop under the influence of gravity. Keeping the drop height consistent eliminates that variable and focuses solely on the effect of mass on the fall.
Use the table of criteria for an investigation to answer the question.
Effect of Object Mass and Drop Height on Gravitational Study
Object To Be Dropped Drop Height (meters)
10-gram ball 5
5-gram ball 8
18-gram ball 10
